Figs. 1 and2 ofJapanese Patent Application Laid-Open No. 5-109542 - In the reactor unit disclosed in
Japanese Patent Application Laid-Open No. 5-109542 - A curable resin such as epoxy resin or the like is used as the resin insulant that is high in thermal conductivity. Shrinkage or the like of the resin occurring during curing thereof causes problems. That is, the resin insulant in the metal box-type case is detached from an inner face thereof, and the metal box-type case undergoes deformation such as distortion or the like.
- Hence, in order to prevent such detachment or deformation, there has been known another technology. According to this technology, a basket body made of a metal and having one open face, reactor bodies accommodated in the basket body, a lid body made of a metal and closing an open end of the basket body, and a curable mold resin filling the interior of the basket body are provided. Eight spaces to be filled with the mold resin are formed between the reactor bodies and the lid body. These spaces are separated from one another by a pair of cruciform spacers and a plate-type spacer located between the cruciform spacers. The spaces thus defined serve to reduce shrinkage ratio of the mold resin. For instance, such a technology is disclosed in Paragraph 0007 and
Figs. 1 and2 ofJapanese Utility Model Application Laid-Open No. 4-133486 - A reactor unit constructed as described above and disclosed in
Japanese Utility Model Application Laid-Open No. 4-133486 - In order to solve the problems stated above, the invention provides, as an exemplary embodiment thereof, a reactor unit which can be prevented from being deformed due to shrinkage of a mold resin occurring during curing thereof.
- First of all, therefore, there is provided a reactor unit comprising a basket body, a plurality of reactor bodies, a lid body, and a mold resin. The basket body has one open face and is made of a metal. The reactor bodies are accommodated in the basket body. The lid body is made of a metal and closes an open end of the basket body. Outlet holes are formed in the lid body. The mold resin is a curable resin. The basket body is filled with the mold resin, with a coil of each of the reactor bodies having been drawn out from a corresponding one of the outlet holes of the lid body. This reactor unit is characterized in that at least one partition, which is located between the reactor bodies and whose leading end extends from an inner face of at least one of the basket body and the lid body and abuts on an inner face of the other, is formed protrusively.
- According to the reactor unit thus constructed, the basket body made of the metal has one open face, and the open end of the basket body is closed by the lid body made of the metal. The partition, whose leading end extends from the inner face of one of the basket body and the lid body and abuts on the inner face of the other, is formed protrusively. The reactor bodies are accommodated in the basket body such that the partition is located between the reactor bodies. The basket body is filled with the curable mold resin, with the coil of each of the reactor bodies having been drawn out from a corresponding one of the outlet holes formed in the lid body.
- Thus, even if the mold resin filling the interior of the basket body has shrunk while curing, the lid body can be prevented from being deformed because the inner face of the lid body abuts on and is supported by the partition.
- According to a further aspect of the invention, it is also preferable that the partition be formed integrally with at least one of the basket body and the lid body.
- According to a further aspect of the invention, it is also preferable that the partition be so formed as to extend substantially across an entire depth of the basket body.

Figs. 1A, 1B , and2 , areactor unit 11 includes abasket body 12 made of a metal exhibiting a relatively high thermal conductivity, for example, of aluminum or the like, a plurality ofreactor bodies 13 accommodated in thebasket body 12, a plate-type lid body 14 made of a metal exhibiting a relatively high thermal conductivity, for example, of aluminum or the like, and acurable mold resin 15 with which thebasket body 12 is filled. - The
basket body 12 has one open face. Anopen end 12a of thebasket body 12 is closed by thelid body 14. A brim-type flange 12b for fixing thelid body 14 is integrated with thebasket body 12. Twopartitions 12d formed as rising walls are integrated with thebasket body 12 in such a manner as to protrude from an inner bottom face (inner face) thereof. - Leading ends of the
partitions 12d are extended so far as to abut on a bottom face (inner face) 14a of thelid body 14 when theopen end 12a is closed by thelid body 14. Thepartitions 12d cooperate with awall face 12e to form threeaccommodation spaces 12f into which the interior of thebasket body 12 is equally divided. Thewall face 12e faces thepartitions 12d of thebasket body 12. In addition, anotch 12g is formed in each of thepartitions 12d at a position close to theopen end 12a. Awire 16 for a temperature detector (not shown) provided in thebasket body 12 is located in thenotch 12g. The temperature detector is provided to detect a temperature of each of thereactor bodies 13. A thermistor or the like is employed as the temperature detector. - Each of the
reactor bodies 13 includes aniron core 17 and a pair ofcoils 18 wound around theiron core 17. Crimp contacts (not shown) are fitted to leading ends of thecoils 18. - Outlet holes 14b are formed in the
lid body 14. An end of each of thecoils 18 passes through a corresponding one of the outlet holes 14b. Thewire 16, which is extended from the aforementioned temperature detector and which is so disposed as to pass through thenotch 12g of a corresponding one of thepartitions 12d, is drawn out from one of the outlet holes 14b. - A curable resin exhibiting insulating properties, for example, epoxy resin or the like is employed as the
mold resin 15. Each of theaccommodation spaces 12f is filled with themold resin 15 flowing from a corresponding one of the outlet holes 14b, such that themold resin 15 surrounds each of thereactor bodies 13 accommodated in a corresponding one of theaccommodation spaces 12f. In this case, a surplus of themold resin 15, which results from differences among amounts of themold resin 15 with which theaccommodation spaces 12f are filled, is supplied to an adjacent one of theaccommodation spaces 12f from a gap formed between thenotch 12g and thewire 16. As a result, themold resin 15 can be supplied to theaccommodation spaces 12f homogeneously. - In the aforementioned construction, the
reactor unit 11 has thereactor bodies 13 accommodated in theaccommodation spaces 12f of thebasket body 12 respectively. After the temperature detector has been accommodated in an arbitrary (preferably central) one of theaccommodation spaces 12f, the end of each of thecoils 18 of each of thereactor bodies 13 is drawn out from a corresponding one of the outlet holes 14b of thelid body 14. While being so disposed as to extend along thenotch 12g, thewire 16 is drawn out from a corresponding one of the outlet holes 14b. - In this state, while the
coils 18 and thewire 16 that have been drawn out from the outlet holes 14b are maintained in a suitably strained state, theopen end 12a is closed by thelid body 14. Then, themold resin 15 is fed from each of the outlet holes 14b (or an arbitrary one of the outlet holes 14b). - The
mold resin 15 is thereafter cured. Because of a reduction in volume resulting from division of the interior of thebasket body 12 into theaccommodation spaces 12f and abutment of the leading ends of thepartitions 12d on thebottom face 14a of thelid body 14, shrinkage of themold resin 15 occurring during curing thereof does not lead to deformation of thelid body 14. - Further, since the
partitions 12d are integrated with thebasket body 12, thebasket body 12 can also be prevented from being deformed. -

basket body 22 has one open face. Anopen end 22a of thebasket body 22 is closed by thelid body 24. Thebasket body 22 has a brim-type flange 22b for fixing thelid body 24. -
Partitions 24d are integrated with a bottom face (inner face) 24a of thelid body 24 in such a manner as to protrude therefrom. When theopen end 22a is closed by thelid body 24, thepartitions 24d abut on a bottom face (inner face) 22c of thebasket body 22. Outlet holes 24b are formed in thelid body 24. An end of each of thecoils 18 passes through a corresponding one of the outlet holes 24b. - The
wire 16 for a temperature detector (not shown) provided in thebasket body 22 is drawn out from one of the outlet holes 24b. Thewire 16 is so disposed as to pass through anotch 24g formed in each of thepartitions 24d at a position close to thebottom face 24a. The temperature detector is provided to detect a temperature of each of thereactor bodies 13. A thermistor or the like is employed as the temperature detector. - Each of the
accommodation spaces 22f is filled with themold resin 15 flowing from a corresponding one of the outlet holes 24b, such that themold resin 15 surrounds each of thereactor bodies 13 accommodated in a corresponding one of theaccommodation spaces 22f. In this case, a surplus of themold resin 15, which results from differences among amounts of themold resin 15 with which theaccommodation spaces 22f are filled, is supplied to an adjacent one of theaccommodation spaces 22f from a gap formed between thenotch 24g and thewire 16. As a result, themold resin 15 can be supplied to theaccommodation spaces 22f homogeneously. - In the aforementioned construction, the
reactor unit 21 has thereactor bodies 13 accommodated at suitable locations of thebasket body 22. After the temperature detector has been accommodated in an arbitrary (preferably central) one of theaccommodation spaces 22f, the end of each of thecoils 18 of each of thereactor bodies 13 is drawn out from a corresponding one of the outlet holes 24b of thelid body 24. While being so disposed as to extend along thenotch 24g, thewire 16 is drawn out from a corresponding one of the outlet holes 24b. - In this state, while the
coils 18 and thewire 16 that have been drawn out from the outlet holes 24b are maintained in a suitably strained state, theopen end 22a is closed by thelid body 24. Then, themold resin 15 is fed from each of the outlet holes 24b (or an arbitrary one of the outlet holes 24b). - The
mold resin 15 is thereafter cured. Because of a reduction in volume resulting from division of the interior of thebasket body 22 into theaccommodation spaces 22f and abutment of the leading ends of thepartitions 24d on thebottom face 22c of thebasket body 22, shrinkage of themold resin 15 occurring during curing thereof does not lead to deformation of thelid body 24. - In each of the aforementioned first and second embodiments, each of the
reactor bodies 13 is spaced from a corresponding one of thepartitions wall face 12e of thebasket body 12 or awall face 22e of the basket body 22) by a gap. However, each of thereactor bodies 13 may be disposed with this gap being eliminated. That is, the gap between each of thereactor bodies 13 and the wall face of a corresponding one of thepartitions wall face basket body 12 or 22) may be filled with the mold resin. - In such a case, therefore, according to an assembly procedure of the first embodiment for example, while the
reactor bodies 13 are accommodated on the side of thebasket body 12, theopen end 12a is closed by thelid body 14. - In the second embodiment, it is possible to adopt an assembly procedure wherein the
basket body 22 is so fitted to thelid body 24 as to cover it while thereactor bodies 13 are retained on the side of thelid body 24, as well as the aforementioned assembly procedure wherein thereactor bodies 13 are accommodated at suitable locations. - In each of the aforementioned embodiments, the
partitions basket body partitions notch - The reactor unit of the invention is constructed as described above and thus can be prevented from being deformed due to shrinkage of the mold resin occurring during curing thereof.
